WATER-PURIFIER.

Specification of Letters Patent.

Patented Nov. 20, 1906.

Original application filed September 8, 1905, Serial No. 277,526. Divided and this application filed January 15, 1906. Serial No. 296,092.

To all whom it may concern.-

Be it known that I, JOHN BOWEY, Jr., of the city of London, in the county ofMiddleseX, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Water-Purifiers, of which the following is a specification.

This invention relates to improvements in that class of apparatus used for treating boiler feed-water with chemicals to precipitate injurious substances held in solution, and my object is to devise apparatus in which the water to be treated is automatically measured by intermittent rotary motion in one direction.

With this object in view my invention con sists, essentially, of the constructions herein after s ecifically described and then definitely c aimed.

Figure 1 is a side sectional elevation of my improved apparatus. Fig. 2 is an elevation of the inner side of the rotatable water-receptacle and related parts. Fig. 3 is a plan view of the tipping detent of the water-receptacle. Fig. 4 is a side elevation of the same. Fig. 5 is a perspective view of the catch preventing back motion of the waterreceptacle. Fig. 6 is a sectional elevation showing the connection of one of the cups.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

1 is a rotatable water-receptacle secured to the shaft 2, suitably journaled on the frame of the apparatus. This water-receptacle is divided by partitions 3 into chambers 4. The partitions are preferably, though not necessarily, double, as shown. The partition forming the right-hand side of each chamber is preferably extended to form a spout 5 to direct the contents of the chamber into the vertical conduit 6, as hereinafter described.

Each chamber toward its right-hand side is preferably provided with a partial cover 7, extending to within a short distance of the partition, thus leaving an opening for the discharge of the water. The slzeof this opening may be regulated by means of a slide 8, adjustably secured to the cover 7, as shown.- Each chamber is provided in its side with an overflow-weir 9, so located that each weir when uppermost is over the upper end of the overflow-conduit 10.

It will be noted that the sides of the waterchamber are extended out past the ends of the projecting partitions 3, and these corners are stiffened and strengthened by the diagonal straps 11. These corners are adapted to engage the buffer-beam 12 of the tipping detent 13. (Shown more particularly in Figs. 2, 3, and 4.) This detent is pivoted at 14 on the frame of the apparatus. At one side of the pivot the detent is provided with a waterpan 15, located below the lower end of the overflow-conduit 10.

At the other side of the pivot a curved arm 16 extends substantially concentric with the periphery of the water chamber. Below this arm a weight 17 is adjustably secured to a suitable brace, so that it may be adjusted to cause the tipping detent to normally tend to maintain the position shown in Fig. 2.

The tipping detent operates as follows: It will be noticed that when the rotary water.-

receptacle is in engagement with the bufferbeam 12 the upper chamber 4 is overbalanced slightly to the right, so that as it is filled from an overhead spout 18 the weight of the water in it tends to rotate the receptacle. As soon as the chamber fills to the level of the overflow-weir 9 the surplus water flows out and down through the conduit 10, filling the pan 15. The added weight in the pan overbalances the detent and draws the bufier-beam 12 away from the receptacle, releasing the same and allowing it to rotate. The tipping of the chamber allows the water to flow from-the spout 5 into the vertical conduit 6. As it is necessary to allow the tippingdetent to resume its normal position, some means must be provided to discharge the water from the pan 15. Various devices might be employed for this purpose. In Fig. 4 I show the bottom of the pan provided with a valve 19, normally closing an opening in the bottom of the pan, but movable in an upward direction. Below the valve I form a suitable pin or projection 20 on the spout 21, secured to the lower end of the vertical conduit 6. When the pan drops, the valve is pushed open by the pin and the water allowed to escape.

It will be noted that the water-receptacle is provided with a series of projections 22, preferably in the form of friction-rollers, which are adapted to engage the curved arm 16. To restore the tipping detent to its normal position, with the buffer-beam in position to engage the corners of the spouts 5, the rest 23 is preferably provided. It is engaged by the under side of the arm 16 when the detent is in its normal position.

The buffer-beam 12 is, it will be seen, particularly on reference to Figs. 3 and 4, secured ease the blow.

The pivots 26 are so located that the bufferbeam tends normally to assume the position shown in Fig. 2, with the heel of the frame in contact with the stop-bar 29. When the tipping detent is overbalanced by the overflow of water, the frame 25 tips, as shown in Fig. 4, and draws the buffer-beam easilyfrom the corners of the spout 5.

Friction-rollers 30 are provided on the edge of the buffer-beam to reduce the friction as the corners draw ast the buffer-beam.

To prevent bac motion of the water-receptacle, I provide the swinging catch shown more particularly in Fig. 5. This comprises a bar 31, journaled horizontally on the frame of the machine adjacent to one of the faces of the water-receptacle. One end of this bar is turned upwardly and has a bevel-sided end 32 secured thereto in the path of a series of lugs 33, secured to the side of the receptacle.

A torsion-spring 34 engages the bar, and its support tends normally to retain the bevelsided end in the position shown. Each lug 33 as. it comes round engages the beveled side, tips the catch outwardly, and passes behind its end, as shown in dotted lines in Fig. 5. The lugs are so located that one of them is immediately in front of the end 32 'when the spout 5 is in engagement with the bufferbeam 12.

This application is a division of application No. 277,526, dated September 8, 1905, and in Fig. 1 I have shown for the purpose of completeness part of the matter shown in the prior application. For instance, 35 is the chemical-solution holder. The shaft 2 eX- tends across this holder and is journaled thereon. On the shaft are secured beaters 36, which when the shaft is in rotation keep the chemical solution properly stirred. The endless carrier 38 is also shown provided with the buckets 40, which raise the chemical solution and deposit it in the chemical-solution conduit 44, the lower endof which communicates with the vertical conduit 6 through its side.

In-the above description it will be seen that I have devised simple and efiicient means whereby with an intermittent rotary motion the feed-wateris measured, the rotary motion being also adapted to impart movement to the chemical-solution-measuring means.

What I claim as my invention. is

1. In a water-purifier the combination of a rotatable chambered waterreceptac1e, an overflow being provided for each chamber; a pivoted tipping detent adapted normally to hold the chamber from rotation; a Water-pan carried by the tipping detent; a conduit adapted to receive Water from the chamberoverflows and lead it into the pan; an arm on the detent; and a part on the water-receptacle adapted to engage the arm to restore the detent to its normal position after it has been tipped by the filling of the pan, substantially as described.
